#Can't use std.fs.watch on M1 Mac

I tried to use the test case in the watch.zig file from the std source as an example to listen to changes to a text file. But I'm getting an error I can't figure out when initializing the watcher:

watch.zig:146:59: error: container 'std.hash_map.HashMapUnmanaged([]const u8,*std.fs.watch.Put,std.hash_map.StringContext,80)' has no member called 'init'
  .file_table = OsData.FileTable.init(allocator),

watch.zig:283:33: error: container 'std.os' has no member called 'EVFILT_VNODE'

The only difference between the test case I used as an example and my code is that I'm using a std.heap.page_allocator which is what I pass to the Watch init var watch = try std.fs.Watch(void).init(allocator, 0);. Maybe that's related to the issue?

Can anyone help me on how to solve or debug this? Thanks!

std.fs.Watch is likely bitrotted, it's not used internally for anything and it has no tests at all

I guess that explains it haha is there any sources I can look at to manually implement a file watcher?

You could start with the code in std/fs/watch.zig and fix it as needed. File watching is OS-specific, so you could pull out just the parts for the OS you need.

If it goes well you could consider contributing fixes to the Zig code.
